a kind of potential sweep method for studying electrode processes, where the sweep direction is inverted at a certain, chosen potential,the voltammetric waveshape obtained for slow and fast electrode reactions is analysed. 详见《Electrochemistry--Principles, methods, and applications》,Christropher M.A. Brett and Ana Maria Oliveria Brett, Oxford University Press |

| Cyclic Voltammetry (CV) is an electrochemical technique which measures the current that develops in an electrochemical cell under conditions where voltage is in excess of that predicted by the Nernst equation. CV is performed by cycling the potential of a working electrode, and measuring the resulting current. |

wikipedia的定义 Cyclic voltammetry or CV is a type of potentiodynamic electrochemical measurement. In a cyclic voltammetry experiment the working electrode potential is ramped linearly versus time like linear sweep voltammetry. Cyclic voltammetry takes the experiment a step further than linear sweep voltammetry which ends when it reaches a set potential. When cyclic voltammetry reaches a set potential, the working electrode's potential ramp is inverted. This inversion can happen multiple times during a single experiment. The current at the working electrode is plotted versus the applied voltage to give the cyclic voltammogram trace. |
